Enable the RSAT features for ADUC by going to the Control Panel and select Programs > Programs and Features > Turn Windows features on or off. Alternatively, you can also click Start and start typing in Turn Windows features on or off and select the option from the menu.

Scroll down to and expand Remote Server Administration Tools.

Expand Role Administration Tools.

Expand AD DS and AD LDS Tools.

Expand AD DS Tools

Check option for Active Directory Administrative Center. This will automatically check all the required options in the parent and sub tree.

Click OK.

You can access ADUC via several methods.

Start Orb > dsa.msc.

Open an MMC console and add the snap-in.

Control Panel > Administrative Tools.

Start > All Programs > Administrative Tools (After it has been indexed by Windows).

The Exchange tabs will not be included by default. To have those, install the Exchange System Management tools. See below.

Run the msi file with the /q switch to avoid message that you are not running Windows Vista, i.e. esmvista.msi /q (extension necessary because there will also be the .exe in the same path).

Exchange System Manager can be found under Start > All Programs > Microsoft Exchange.

Adding the Exchange tabs for user properties:

You may notice that the Exchange tabs are missing from user properties in ADUC. This is because the console is running in 64 bit mode and does not plugin into the 32 bit Exchange System Manager. To overcome this:

Right-click ADUC select Send To > Desktop (Create Shortcut)*.

Right-click the shortcut and go to Properties.

Change the target path to include -32

If you prefer creating an MMC with multiple snap-ins such as ADUC and ESM:

Go to Start Orb > Search\Run (or Windows+R).

Type mmc -32 and launch.**

Go to File > Add/Remove Snap-In.

Add ADUC, ESM, and whatever additional snap-ins you need.

Save.

*Alternatively, you can run dsa.msc -32 from Run (Windows+R) or the Start Orb > Search/Run

**You must run the mmc with the 32 bit switch, otherwise the 32 bit Exchange System Management add-in will not be available in the list of snap-ins.

Note, the Terminal Service tab is now known as the Remote Desktop Services Profile tab. Further, you will not see this tab if you run dsa.msc or your mmc in 32 bit mode so consider creating two shortcuts with and without the 32 bit switch.
